6.3 Plan and Build the AC Trunk Cable
AC Trunk Cable is used to connect the micro inverter to the power distribution box.
A ) Select the appropriate AC Trunk Cable according to the spacing between micro inverters. The connectors of the AC
Trunk Cable should be spaced based on the spacing between micro inverters to ensure that they can be properly matched.
(Rockcore provides AC Trunk Cable with different AC Trunk Connector spacing.)
B ) Determine how many micro inverters you plan to install on each AC branch and prepare AC Trunk connectors
accordingly.
C ) Take out segments of AC Trunk Cable as you need to make AC branch.
Strip cables：Only multiple strands of
copper wire can be used. Please cut and strip
the wire according to the requirements, and
the ground wire needs to be 5mm longer
than live and naught wire, and the applicable
stripping length is 7 ~ 8mm.
Instruction of cable connector assembly：
Screwing off the tail parts (End Locker, ) from
male or female cable connector，and then
pulling the wire which was cut and stripped
through them in turn.
Crimp the wire: Inserting the stripped wires correctly
into the corresponding pin holes according to the
identification and then tightening all screws firmly,
Screw twisting torque 0.4±0.1N·m. after it , giving a
reverse pull force lightly ( about 10N ) by manual to test
crimping result. Please pay attention to avoiding damage
of pins and pin-holder. After crimping, The tensile
strength shall meet the requirements listed in the
followingtable：
Conductor cross-section area (mm2)
Required tensile strength (N)
Install male & female cable body to plastic housing: Push
the male or female cable body into housing body correctly
according to the position of theclamping groove , and will
hear a crisp “click” sound in place.
